    • A valve (61) for enabling release of pressurized steam from a pressure vessel has a displaceable closure member (67) which is maintained in its closed disposition by exposure to the pressure of the steam within the pressure vessel. The closure member (67) is displaced between its closed disposition and an open disposition by a double-acting actuator (69), suitably an air-driven piston/cylinder device, the closure member (67) being preferably mounted at one axial end of a spindle (68) extending between the closure member (67) and the actuator (69). The closure member (67) is suitably mounted for substantially metal-to-metal contact with a valve seat portion (63), without interposition of any sealing element, preferably for substantially vertical displacement between its closed and dispositions.
    • 用于使加压蒸汽能够从压力容器释放的阀(61)具有可移动的关闭构件(67),该关闭构件通过暴露于压力容器内的蒸汽的压力而保持在其关闭的布置中 。 闭合构件6​​7通过双作用致动器69适当地由空气驱动的活塞/缸体装置在其闭合布置与打开布置之间移位,闭合构件6​​7优选地安装在 在关闭件(67)和致动器(69)之间延伸的心轴(68)。 封闭构件(67)被适当地安装用于基本上与阀座部分(63)进行金属与金属的接触,而不需要插入任何密封元件,优选地用于在其关闭和设置之间的基本垂直位移。
